[XFS] convert xfs_getbmap to take formatter functions
Preliminary work to hook up fiemap, this allows us to pass in an arbitrary formatter to copy extent data back to userspace. The formatter takes info for 1 extent, a pointer to the user "thing*" and a pointer to a "filled" variable to indicate whether a userspace buffer did get filled in (for fiemap, hole "extents" are skipped). I'm just using the getbmapx struct as a "common denominator" because as far as I can see, it holds all info that any formatters will care about. ("*thing" because fiemap doesn't pass the user pointer around, but rather has a pointer to a fiemap info structure, and helpers associated with it) Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Niv Sardi <xaiki@sgi.com>
